What’s the difference between 1985 and 1986 /1987/1988 Honda TRX250 rear foot brake cables? Partzilla shows the cable for my ‘85 as #43470-HA8-000 but different part numbers for ‘86/‘87/‘88 models. What could possibly have caused Honda to use different cable part numbers for these identical quads? What are the differences?

Difference?

43470-HA8-680 superseded to 43470-HA8-770 (85 and 86 are the same)

1985 - the TRX250 was introduced

1986 - the TRX250 was upgraded slightly and the TRX250R was introduced with hydraulic rear brake

1987 - the TRX250 was upgraded slightly, The TRX250R was upgraded and the TRX250X was introduced

1988 - the TRX250 was dropped and only the TRX250 R and X were offered - Both the R and X had a hydraulic rear brake

The cable is the same for 85, 86 and 87 TRX250 - no cable on the R or X

Thanks for reply. I don’t know why all the listings I see for TRX250 Fourtrax always state that the application is for 86,87. Never a mention of 1985.

Because 43470-HA8-770 is for 86 and 87 - 43470-HA8-680 was the part number for 1985, but the number superseded to 43470-HA8-770 making the cable the same for 85, 86 and 87

The cable on my ‘85 TRX250 seems to be 1/4”-3/8” too short. It’s a stock cable but maybe the PO installed the wrong one? It’s stretched pretty tightly between the foot brake bracket and the integrated cable mount in the aluminum rear drum brake housing. There’s nearly no slack/loop at all. It’s not a matter of cable adjustment. The metal “shoulders” on the ends of the cable casing don’t reach far enough to provide support for the return spring to work well. My parking brake cable has no problem.

Return spring? The return spring is on the cam arm (#11)

The springs (#16) are anti-rattle springs - they just take slack out of the cable so the lever at the handlebar does not rattle from vibration.

I suggest you have a sticky cable or the assembly is not assembled correctly ib=n some fashion.
